Hi, I'm almost sure it depends on Qt-Version. With LyX on Mac with Qt4 we have two fundamental problems: 1. Qt4 with Carbon crashes when interacting with some desktop tools like Divvy or SizeUp http://www.lyx.org/trac/ticket/7365 and http://www.lyx.org/trac/ticket/7519 2. Qt4 with Cocoa is painting text with kerning hints This doesn't match with the drawing engine of LyX and LyX's cursor movement. See the discussion here: http://www.mail-archive.com/lyx-devel@lists.lyx.org/msg169152.html I've build 2.0.2 on Mac with Qt4.7 where Cocoa is the default to avoid (1). The drawback is we have to deal with (2) - the current solution is to draw text just char by char, the text fragments are only one character long. To check if this is the culprit one may add the following line to your preferences file: \force_paint_single_char false On a Mac this is the file "~/Library/Application Support/LyX-2.0/preferences". (Broken cursor placement for long lines should be one consequence.) Stephan
